We propose a novel yet practical method capturing an individual's research or innovation performance by the shape centroids of the h-core and h-tail areas of its publications or patents. A large number of individuals’ relative performance with respect to their h-cores and h-tails can be...

Using the concepts of h-core and h-tail, shape descriptors and shape centroids, k-index and k′-index, dynamic measures are probed, with practical data in the fields of Physics and sociology. It is revealed that there are obvious differences between natural sciences (Physics, particles &...
